Can a loose cervix cause miscarriage?

Cervical relaxation may lead to miscarriage, but it is not absolute. There are many reasons for cervical relaxation. Sometimes, cervical relaxation can prolong pregnancy and reduce miscarriage rate through external intervention. The specific situation is analyzed as follows:

For women with loose cervix, it may be due to cervical incompetence, which shortens the cervical canal and causes premature rupture of membranes in the second and third trimesters, leading to miscarriage. However, it may also be due to congenital factors, especially weak local muscle fibers. Regardless of which factor causes cervical relaxation, correction is needed to avoid habitual miscarriage.

Generally, miscarriage or premature birth is more likely to occur between 16 and 28 weeks of pregnancy. For women with loose cervix, they need to pay more attention to bed rest after the second trimester of pregnancy and try to reduce exercise. At the same time, they should pay more attention to prohibiting sexual intercourse to avoid miscarriage. If necessary, they need to undergo cervical cerclage surgery under the guidance of a doctor to avoid another miscarriage or premature birth, but they need to go to the hospital in time to remove the sutures when the due date arrives.
